How to Gracefully Shut Down Kubernetes Pods Without Losing Traffic

During a Kubernetes deployment, the old pod is terminated while the new one starts, and by adding a preStop hook and properly configuring terminationGracePeriodSeconds, you can ensure graceful shutdown, propagate SIGTERM to all processes, avoid traffic loss, and handle signal forwarding for multi‑process containers.
